During slurry preparation for Slurry TBM operation, several parameters are critical to monitor to ensure the slurry has the desired properties for face support and efficient transport of excavated material. Slurry density is important because it directly affects the slurry's ability to balance earth and water pressures at the tunnel face. Density is typically controlled by adjusting the concentration of solids in the slurry. Viscosity influences the slurry's flow behavior and its ability to form a stable filter cake on the excavation face. Viscosity is ....
